I checked and the portaudio-19_pre20071207/work/portaudio/bindings/cpp/lib/Makefile contains the following: libportaudiocpp_la_DEPENDENCIES = \ $(top_builddir)/$(PORTAUDIO_ROOT)/lib/libportaudio.la However, the $(top_builddir)/$(PORTAUDIO_ROOT)/lib/ directory (which translates to "../../../lib" since top_builddir=.. and PORTAUDIO_ROOT=../..) was empty. I have since emerged the package individually with success, so this is an intermittent problem. I suspect a race condition triggered by a missing dependency somewhere; I've been seeing this in several different packages lately (bug 351663 and bug 352198, for example). I will attach build.log and emerge --info output.
Created attachment 261095 [details] build.log
Created attachment 261097 [details] emerge --info =media-libs/portaudio-19_pre20071207
Try 19_pre20110317 instead... that 2007 version is not intresting anymore
